When shooting with focus mode set to AF-A, sometimes the camera does not maintain focus on a moving subject.

Shooting moving subject with focus mode set to AF-A

In AF-A mode, the camera automatically recognizes whether the subject is moving or not, and switches the AF mode between AF-S and AF-C accordingly.

When shooting fast-moving subjects with focus mode set to AF-A, sometimes the AF mode cannot switch fast enough and the camera may not continue to focus on the moving subject.In such cases, we recommend setting the focus mode to AF-C.
